Basic procedure of a quantitative design 01 Make observations about something unknown or unexplained. 02 Investigate current theory about your problem or issue, 03 Hypothesize for observations. 04 Make a prediction of outcomes based on the hypotheses. 05 Formulate a plan to test your prediction. 06 Collect and process your data. 07 Verify and present your findings. 08 Make your final conclusions

Methods Types of methods Are they quantitative or qualitative? If the research objective is to formulate only secondary research,then annual reports,censuses, articles,books etc.are used. 02 If the research objective is to collect first hand data, then the researcher devices -questionnaire -observation -interview

general There are six main stages in the production of plastic paper clips from this small factory.Two of these stages involve actual preparation of the clips,while the other four consist of quality control before the clips are sent out from the factory to the retailers to be sold to the public
